Graphs: Numeric Label Format

When you create a graph with numeric labels, it's possible to use the Format String field to specify the exact numeric format. For instance, the value %d will display the numeric values as integers, whereas the value %0.2f will display them as decimal numbers with two decimal places.

The following list summarizes possible values for this field. If you are familiar with programming you will notice that it's identical to the format directives of the printf/sprintf functions.

% - a literal percent character. No argument is required.

b - the argument is treated as an integer, and presented as a binary number.

c - the argument is treated as an integer, and presented as the character with that ASCII value.

d - the argument is treated as an integer, and presented as a (signed) decimal number.

e - the argument is treated as scientific notation (e.g. 1.2e+2). The precision specifier stands for the number of digits after the decimal point since PHP 5.2.1. In earlier versions, it was taken as number of significant digits (one less).

E - like %e but uses uppercase letter (e.g. 1.2E+2).

f - the argument is treated as a float, and presented as a floating-point number (locale aware).

F - the argument is treated as a float, and presented as a floating-point number (non-locale aware). Available since PHP 4.3.10 and PHP 5.0.3.

g - shorter of %e and %f.

G - shorter of %E and %f.

o - the argument is treated as an integer, and presented as an octal number.

s - the argument is treated as and presented as a string.

u - the argument is treated as an integer, and presented as an unsigned decimal number.

x - the argument is treated as an integer and presented as a hexadecimal number (with lowercase letters).

X - the argument is treated as an integer and presented as a hexadecimal number (with uppercase letters).
